The present research aims at collecting plants names from '' Al –Muheet fi Al- Lugha '' by Al –Sahib bin Abbad (385 A .H .) ,then the data documenting from the books of plants written by Arab linguists and from the dictionaries of linguistics whose authors ,paid a great attention to the names of plants and trees . the choice of ''A-Muheet fi Al-Lugha ''is not a random one , but depended on a knowledge of the patterns of this dictionary , its methodology of writing ,and the nature of its material .lt is one of the dictionaries in which the authors were comprehensive , deductive and inclusive.this is why the book is called ''Al-Muheet'' (comprehensive). In addition to that , Al-Sahib was a great,well-acguainted and knowledgeable linguist who mentioned words which were not mentioned by other dictionary compilers. We, therefore , collected the names of plants mentioned in Al-Muheet in an attempt to compile a dictionary entitled as '' Dictionary of plant Names '' in '' Al- Muheet fi Al-Lugha '' : collection and documentation .the dictionary is confined to names of the plants rather than trees because if we compile a dictionary for both of them the size of the work will be doubled . Before we arrange the vocabulary, we wrote a preface about what is written on plants in our linguistic tradition to show the importance of dictionary we have compiled . our methodology in this research is that we have arranged the names of plants alphabetically and not according to the phonetic system followed by Al-Sahib due to the difficalty of the latter . we have also paid attention to the origin of the vocabulary . we hope that we have accomplished a successful work.
